Five Significant Differences Between Malignant Mesothelioma and Benign Mesothelioma

Tumors come in two kinds, benign and malignant, so does mesothelioma. What makes them different? We can compare from the following five aspects.

1. Cause
As we all know, asbestos exposure gives rise to the malignant mesothelioma, so many countries have banned the use of asbestos. For the benign mesothelioma, unluckily, we are not sure about its cause due to its relatively few cases.

2. Latency Period
Although it is benign, this mesothelioma is able to disturb you at any time in your life. While the malignant mesothelioma has a long latency period, varying from 20-50 years.

3. Mortality Rate
Mesothelioma is never an expected visitor, especially the malignant one. Surgical removal makes a low mortality rate for benign mesothelioma. However, patients with malignant mesothelioma have to suffer a high mortality rate.

4. Metastasis
Speaking of tumors, metastasis deserves the most concern.
A benign mesothelioma is not aggressive. It doesn’t spread. But it doesn’t mean it won’t grow in size. If it happens after surgery, you need to be careful with its relapse or even worse growth.
As to the malignant mesothelioma, the doctors should keep an eye on its spreading to other organs and lymph nodes.

5. Treatment

Treatment choosing not only affects medical effects. A suitable treatment can also make patients feel more comfortable.
Surgery is almost the first choice for benign mesothelioma and it do have a high success rate. Cutting the bad part out will make patients feel like regain health. However, that’s only the first step, Successful treatment also needs follow-ups to monitor for new tumor growth.Sometimes, a mesothelioma may appear benign but recur, spread locally, or become malignant.

For the malignant mesothelioma, doctors will decide the treatment in terms of the tumor and the patient’s condition, usually palliative.
The most common three treatments are surgery, chemotherapy, and radiotherapy.


Overall, you can have a general understanding of mesothelioma.
